Where margin leaks in a wholesale distribution business— and how to stop it
In distribution, margin rarely collapses in a single bad quarter. It leaks — quietly, a fraction of a point at a time, through decisions nobody records and prices nobody reviews. Revenue gets watched daily; margin gets discovered at month-end. By the time it shows up in the accounts, the leak has been running for months.
Run the arithmetic on your own business before reading further. At a 25% gross margin, an unplanned 2.5-point discount hands away 10% of the gross profit on that sale — and to recover it, you need roughly 11% more volume just to stand still. Ask yourself which is harder: finding 11% more volume or stopping the discount. Every unplanned discount is margin leaking silently. Here are the five leaks I saw most often in thirteen years running a distribution business and closed to help grow it more than 15x.
Leak 1: unplanned discounting
A planned discount is a pricing decision: volume breaks, contract terms, a strategic account. An unplanned discount is a salesperson buying a deal with your margin because it is the easiest lever in the room. The fix is governance, not exhortation: a written discount-authority matrix (who can approve what, to what floor), and a weekly report of every discount given, by rep, against that authority. What gets inspected stops leaking. The deeper fix is capability — a sales team that can defend price with evidence of value in the customer’s numbers doesn’t need the discount. That is the Differentiation pillar of The TRADE Selling System.
Leak 2: averages hiding the truth
A healthy blended margin can hide a long tail of customers and SKUs you serve at a loss once cost-to-serve is counted — small orders, special freight, extended credit, endless technical support. Cut the data by customer and by SKU quarterly, fully costed. Then act on the tail: reprice it, restructure how it is served (minimum order values, web- only service), or let it go politely. Most owners are shocked by how much of their effort earns nothing.
Leak 3: landed-cost drift
For importers this is the quiet killer. Sea freight moves, currency moves, suppliers reprice — and your price list gets reviewed once a year. Every month between a cost increase and a price response is margin gone forever. Maintain a live landed-cost model per SKU (unit cost, freight, duty, currency at today’s rate, not last year’s) and set trigger-based repricing: when landed cost moves more than an agreed threshold, prices are reviewed that month, not at the annual reset.
Leak 4: stock that doesn’t move
Slow-moving stock leaks margin twice: it ties up working capital that could fund stock that sells, and it ends its life marked down. Watch stock turns by category, not just in total, and run a disciplined quarterly range review — every SKU earns its shelf space or exits while it still has value. In distribution, the discipline to delete products is worth as much as the judgement to add them.
Leak 5: nobody owns price
In many distribution businesses, pricing belongs to everyone and therefore no one: sales want it lower, finance wants it higher, and the price list reflects whoever pushed last. Give margin a seat in the weekly operating rhythm — one owner, one weekly view of margin by customer, category and rep, and a standing agenda item. Margin is a system you run, not a result you hope for.
The structural lever: your own brand
The five fixes above protect the margin you have. Private label changes the margin you can have. At 4Cabling we built our own-brand range to roughly 70% of revenue, which strengthened both margin and control of the supply chain. We did not start everywhere — we started in categories where we had the volume to justify it and where customers bought on availability and specification rather than brand. If you import at any scale, this is the long-term margin question worth the most thought.

Then close the leaks in the order above: governance first, because it costs nothing and starts working this week.
